Aquatic product processing is the process of transforming aquatic raw materials into products with shape, quality, and value, and weighing is the key link. As an important part of the marine industry, the development of aquatic product processing is promoted by marine engineering technology and marine equipment intelligence. With the continuous development of marine engineering technology and the continuous intelligence and automation of marine equipment, the application of dynamic weighing technology is increasingly extensive, and its position in the marine industry is also more and more important. Due to the lack of in-depth research in China, the stability and accuracy of the existing weighing sensors are poor, and there is no corresponding professional marine weighing equipment in our country. There are many challenges, such as the marine environment and ship shaking. This paper mainly introduces the background and types of ship weighing, as well as the advantages and disadvantages of existing equipment, and analyzes the technical characteristics of the weighing compensation algorithm and its application advantages in aquatic product processing. Finally, the relevant research and status quo at home and abroad are summarized. In order to solve the dynamic weighing under complex sea conditions, it is necessary to collect and analyze the weighing data under different sea areas, ship types, loads, and working conditions to provide a basis for the optimization and verification of the weighing compensation algorithm. Establishing a marine weighing database can improve the accuracy and reliability of aquatic product quality and provide data support for the development and utilization of marine resources. In order to look forward to the future aquatic product processing industry and other aspects, the marine ship-borne weighing technology is finally realized.
